i965/gen9: Pass alignment as function parameter in drm_intel_gem_bo_alloc_internal()
In case of YF/YS tiled buffers libdrm need not know about the tiling format because these buffers don't have hardware support to be tiled or detiled through a fenced region. But, libdrm still need to know about buffer alignment restrictions because kernel uses it when resolving the relocation. Mesa uses drm_intel_gem_bo_alloc_for_render() to allocate Yf/Ys buffers. So, use the passed alignment value in this function to initialize the align variable in drm_intel_bo. Note that we continue ignoring the alignment value passed to drm_intel_gem_bo_alloc() to follow the previous behavior. V2: Add a condition to avoid allocation from cache. (Ben) V3: Make no changes in cache allocation strategy. Just update the alignment. Update the aperture size estimate including the alignment. (Ben, Chris) V4: Move aperture size adjustments inside drm_intel_bo_gem_set_in_aperture_size() Don't split sentences across the one-line header and the changelog. (Chris) Signed-off-by: Anuj Phogat <anuj.phogat@gmail.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
